Everyone has that thing that they envision will happen when the future is here. For some, it’s flying cars. For me, it’s gyms that create electricity. I mean, there are all of those people sitting in one place, pedaling away on stationary bikes, wouldn’t it be cool if they powered the lights? While I haven’t seen any of those popping up, I did hear about gyms driven by charity that sound pretty cool in the meantime. It takes philanthropy out of the distant future, and makes it a part of everyday life. There are a variety of options to choose from, but most gyms getting on the fund-raising bandwagon donate $1 per student per class to a different charity. In NYC, Studio 360 and The Movement yoga studio offer donations built into the price of your class. Here’s to hoping that more pop up soon, because sweating for a good cause makes it a lot more difficult to come up with an excuse to skip your workout.
